LG.Philips LCD has developed the first full-color flexible active matrix organic light emitting diode (AMOLED) display that uses amorphous silicon (a-Si) technology.
LG.Philips LCD developed this display in cooperation with Universal Display Corporation of the United States, which holds the original patents for Phosphorescent OLED (PHOLED) technology.
LG.Philips LCD?s 4-inch full-color flexible AMOLED display features 320 x 240 QVGA resolution and can reproduce 16.77 million colors. At an ultra thin 150 μm, this display is barely thicker than a human hair. It uses a stainless metal foil substrate for durability and protection against heat.
"This display capitalizes on the strengths of OLED technology and its image quality is really something to behold," said Hyunhe Ha, executive vice president and the head of the Small & Medium Displays Business Unit at LG.Philips LCD. "Although we are still in the initial stages with this technology, we expect to make some exciting advances in the near future."
OLED technology is recognized as an optimal technology for use in flexible displays. Most importantly, using a-Si backplane technology allows LG.Philips LCD to use its existing TFT-LCD production line for these AMOLEDs, a major step toward demonstrating the commercial viability of such products.
In 2006 LG.Philips LCD revealed a 14.1-inch monochrome E-paper display. This year it became the first company to introduce a color version in the same size.
LG.Philips LCD will unveil flexible AMOLED display at SID 2007 in Long Beach, California, on May 20.
